Cookie blocked/not saved in IFRAME in Internet Explorer

Question

I have two websites, let\'s say they\'re example.com and anotherexample.net. On anotherexample.net/page.html, I have an IFRAME S

Answer 1

I was able to make the evil eye go away by simply adding this small header to the site in the IFrame (PHP solution):

header('P3P: CP="NOI ADM DEV COM NAV OUR STP"');

Remember to press ctrl+F5 to reload your site or Explorer may still show the evil eye, despite the fact that it's working fine. This is probably the main reason why I had so many problems getting it to work.

No policy file was neccesary at all.

Edit: I found a nice blog entry that explains the problem with cookies in IFrames. It also has a quick fix in C# code: Frames, ASPX Pages and Rejected Cookies
